CYW43340 - Regional files

[CoryEIMTS]

Customer looking using the CYW43340 is looking to make sure the regional settings for the radio are correct.
During driver loading (we are using a linux based platform) we encounter a warning saying that he CLM blob is missing and that the radio may have limited channels.
All I need to resolve this issue is the regional files (at least one that works in the USA at first) so that I can validate the error goes away and performance is acceptable.

That being said, I’m not sure where to find these files. I can find the radio’s firmware when I look for the Broadcom part, but no such luck for regional files.
Do you know where I might be able to find them they used to be on the Cypress website but are now not on the Infineon website?

Hi

You can find the file here: Cypress-Linux-WiFi-Driver-Release-FMAC-2021-10-20 under the firmware folder (cyfmac43340-sdio.bin).

The clm configurations are integrated within the firmware (.bin file). To verify, you can pass the "wl clmver" command.  The output should look something like this: 

CLM DATA: 9.10.76

CLM Import:  1.36.3

You can also pass the "wl country US" command to set the country region to the USA.

Let me know if you have any doubts here.

Thanks
